5 Warning Signs for Detecting Ransomware Attacks

Ransomware attacks have become more common these days, unfortunately. The criminals behind these attacks aren’t only targeting big companies these days, but others too. It’s not just a couple of thousands of dollars either. They ask for a substantial amount of money.

In that time, you will be facing a difficult decision. It’s either pay the money in untraceable currency or lose your data forever.

Therefore, it’s essential to detect the attacks before they actually take place. Criminals who do these kinds of attacks don’t just randomly wake up one day and think they will attack a business. In fact, they plan their attacks carefully.

It’s because of that planning that they often leave hints in your system. If anyone in your organization can identify those signs, you can call a ransomware investigation service and be safe.

So, let’s take a better look into five giveaways of an imminent ransomware attack.

Test Attacks

Any attacker will first need to test your systems by launching a series of small and isolated attacks. Generally, these are across multiple machines to raise fewer eyebrows.

These test attacks can show the hacker how easily or effectively their ransomware can get through your cybersecurity.

While the attackers are launching these attacks for their benefit, you can use them as well. These test runs are dead giveaways of an imminent attack.

MimiKatz

MimiKatz is a tool quite popular among hackers. Generally, a hacker will use MimiKatz with the Microsoft Process Explorer to correctly identify everyone’s login details in your organization. They could also only target the key players in the company.

The Microsoft Process Explorer is not a harmful or fraudulent tool. It’s completely legitimate. However, a hacker can use the application to dump LSASSE.exe run files from the system’s memory. Then they create a .dump file that is taken to the hacker’s environment. It is there that they use MimiKatz to get login information.

Therefore, you must investigate any detection of MimiKatz and presume it’s dangerous.

Security-Disabling Applications

Many security-disabling applications exist to help people perform certain tasks. They are entirely legitimate as well. However, they can be disastrous in the hands of a criminal.

If a hacker somehow has admin access to your network, they can quickly deploy these applications. Once in your network, they can eliminate many of your security protocols. Therefore, leaving you quite or entirely vulnerable.

If any of your employees notice any security-disabling application, a proper investigation can help you prevent an attack.

Network Scanners

Many of the more professional criminal hackers try to make their way into a system by searching for information to help them.

For instance, they may be looking to gain access to admin rights. For that, they will look at the relevant admins for any particular system.

To find and manipulate these vulnerabilities, hackers use network scanners. These can be AngryIP or Advanced Port Scanner.

While they do have legitimate uses, you should investigate them if they are on your servers. Trace them back to the source. If someone on your team deployed it, ask them about it.

Repetitive Red Flags

In case your team is repeatedly flagging detections that generally occur at the same time every other day. You should then take that as a sign and investigate those red flags, even if they seem unrelated.

Even if the malware your team detected was removed immediately, you should still investigate them.

The reason is, these red flags are not the main issue. While you may be happy with your team detecting them and taking care of the problem, your system may be becoming more vulnerable with every attack.

Therefore, you should immediately investigate it or hire ransomware investigators to take a look.
